Philip, I have asked you to continue this discussion by PM if you felt it needed further comment.
However, as you have raised further comment in public, I'll address your concerns.
So, a comment suggesting a link might have been appropriate, or a more comprehensive search would have explained the situation in more detail. Certainly going in all guns blazing with an abusive (my opinion is subjective of course) post was, perhaps, not the ideal approach.
No injured feelings :) I moderate on certain fora somewhat less tranquil than here, but thanks anyway.
The idea of a link is one which, quite frankly, didn't occur to me, probably because real life was intruding and my time was limited. However, it is, undoubtedly, a good idea and one I'll address presently.
